The Impac ISR 320 is a fast, digital, non-contact two-color pyrometer designed for precise temperature measurement from 700°C to 2500°C. Using the ratio (two-color) method, it delivers reliable readings even with varying emissivity, dust, or partial obstruction, making it ideal for demanding industrial processes.
